488 PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON NOTE CORRECTIONS TO "J. DOUGLAS HOOD: BIBLIOGRAPHY OF SCIENTIFIC PAPERS, CHIEFLY ON THRIPS, AND INDEX OF NEW NAMES, 1948-1960" C. F. Jacot-Guillarmod, Albany Museum, Grahamstown, Republic of South Africa, kindly called my attention to two titles I omitted from "J-Douglas Hood: Bibliography of scientific papers, chiefly on thrips, and index of new names, 1948-1960," (Proc. Entomol. Soc. Wash. 76(3) :297-309, 1974) and the resultant misnumbering of Hood's last three papers. I omitted Hood's article "Thysanoptera" that appeared in the 1947-1964 printings of the 14th edition of Encylopaedia Britannica and in the re-maining printings of this edition, through 1973, in a shorter and slightly revised fomi. Hood did not assign a number to this article. Also I omitted Hood's paper "The tenns tergum and sternum, tergite and steniite," ( 1958. Systematic Zool. 7(3) : 131-133) which, according to Jacot-Guillamiod, Hood numbered 174. Thus his paper no. 175 was "A note on Monilothrips ketnpi Moulton (Thysanoptera: Thripidae)" by J. Douglas Hood and C. Jacot-Guillarmod (1959. J. Entomol. Soc. S. Africa 22(2): 489-493) and his paper no. 176 was "Six new Thysanoptera from Brazil," ( 1960. Rev. Brasil. Entomol. [Sao Paulo] 9:57-68.) No reprints of Hood's paper no. 174 and the Britannica article are available. However, through the courtesy of Mrs. Helen Hood Smallridge and Mrs. Robin Hood Jansen the System-atic Entomology Laboratory has the remaining supplies of Hood's reprints for distribution to interested thysanopterists.

NOTE THE SQUASH AND GOURD BEES, PEPONAPIS AZTEC A HURD AND LINSLEY AN13 XENOGLOSSA GABBII CRAWFORDI COCKERELL IN CHIHUAHUA, MEXICO (HYMENOPTERA: APOIDEA) Chihuahua is the largest state in Mexico and its northern boundaiy is contiguous throughout with the United States, yet its apoid fauna is rather poorly knowai. Thus, of the 17 species of squash and gourd bees of the genera Pepomipis Robertson and Xenoglossa Smith known from Mexico, Hurd and Linsley (1966. Ann. Entomol. Soc. Amer. 59:835-851; 1967, loc. cit. 60:988-1007) were able to list just two species each of Peponapis and Xenoglossa for Chihuahua, while for the geographically adjacent and
